perimeter of traingle =7cm
and, we know that some of all angles of traingle=360°
so angle P=3/180
P=60°
and angle Q=180-60/2=120/2
Q=60°
and angle R=60+60-180=120-180
R=60°
so,angle P=60°,angle Q=60° and angle R=60°
and, we know that some of all angles of traingle=360°
so angle P=3/180
P=60°
and angle Q=180-60/2=120/2
Q=60°
and angle R=60+60-180=120-180
R=60°
so,angle P=60°,angle Q=60° and angle R=60°
